I'm trying to run the upgrade from 3.5.2 to 3.6 and during the process (accessed via 'install now' in the dashboard get the following error:
Fatal error: Call to undefined function wp_safe_remote_get() in /websites/123reg/LinuxPackage22/ra/ch/el/rachellucie.co.uk/public_html/blog/wp-admin/includes/file.php on line 500
I had deactivated the plug ins, and now can't reactivate them, either, this gives error:
Fatal error: Call to undefined function wp_unslash() in /websites/123reg/LinuxPackage22/ra/ch/el/rachellucie.co.uk/public_html/blog/wp-admin/includes/class-wp-plugins-list-table.php on line 25
123-reg tell me that as this is an issue with the 3rd party package being hosted, this issue is nothing to do with them.
Please can you help!
